SHOCK-ABSORBER- FOB ROAD-VEHICLES.

Specification ot letters Patent. Patented Sepfi i6 1919::

Application filed January 22, 1919. Serial No. 27%428.

To all whom it may concern:

Be it known that I, Lnwrs P. HALLADAY, acitizen of the United States, residing at Str'eator, in the county of La Salle 'and'State of Illinois,'have invented-a certain new and useful Im rovement in Shock-Absorbers for Road-Vehicles, of which the following is a My invention relates-to improvements in shock absorbers or auxiliafy "springs are particularly appropriate for use with the well known Ford automobile. One object is to provide a new and improved form of auxiliary spring suspension wherein a strong and sturdy spring may be used. Another object is to provide a cheap, convenient and satisfactory arrangement making possible the use of a'conical spring with the accompanying'increase in resiliency and flexibility and response to fpressure throughout the entire length thereo Other objects will appear from time to time throughout the specification.

'Figure I is an elevation. of an automobile with parts omitted to show my device; p Fig. 2 is a rearelvation of the front with parts omitted-showing the way in which the device is applied to th front axle of a Ford car;

form" shown. in Figs.

Fig. 3 is a plan view of the spring plat- 1 and 2 with parts in section;'

Fig. 4 is a Fig. 1.

Like pa ts are indicated by like letters in all the figures.

A is the rear axle of the automobile. A is the brake drum. A is a cross type spring. A A are linkspivoted on the spring pin A. at the'end of the spring, the links being arranged of the spring. ad-

section along the line 4-4 of one on e'ther side jacent the ends of the pin.

B is a spring bracket bolted to the brake drum. It is bored outas indicated and carrice .9. round auxilialz Spring platform B is an apertiired caring sleeve at one side of the platform. Through it passes a pivoted. pin B upon either end of which is 'rotatably. mounted the ends of a forked lever B. This forked lever B is elbow shaped as indicated and terminates at its outer ends in a bearing sleeve B through which passes a 'pin B supporting the free ends of the links A.

Qwardly depending such bearing sleeves C as may beused for any type of vehicle but the axis of the coil spring,

a portion of O- is a spiral I shape having its spring seat B broad base-resting upon the preferably surrounding the upper end of the spring and supported thereon. Downfrom this stirrup cap are supporting arms C extending down one on conical spring ofbeehive.

C is a circular stirrup cap I either side of the spring seat and apertured to engage the plus C which pass through at the upper angular central port10n-ofjthe lever infsuch wisethat' a clockwise-rotation of the lever about the pin B will-result in pulling down on the stirrup and compressing the spring. The

parts being .so arranged that when in operative. position with the normal weight on the car, the line joining tially horizontal so that the contraction and expansion of the coil spring will cause that line to move slightly above and below the horizontal position and thus above and below the position of perpendicularity to so that-the twisting or rocking of the spring as a resu t of angular displacement of the stirrup will be minimized and thatthere will be practically no opportunity for the coil spring to as that is all taken care of'by the lever relation.

In Fig. 2 is necessary to adapt this device for the front axle of the car.

D isa spring perch.

and that is done byjust changing the perches putting the right hand. one on. the left end of the axle and vice versa. The bracket D which in. every other respect is the same as the bracket B is provided with a downwardly extending lug D through which passes a pin D" to hold it in position with the bearing surface D resting at D nnthe spring perch D The use and operation of my invention are as follows carry any portion of the twisting load It will be noted that' -it is turned outwardly instead of inwardly the spirit of'my in- B. and C is substan-.

shown the slight modification In applying the device to a motor vehicle in which the old type of spring suspension has been used, the front spring perches are reversed as indicated and the rear spring perches are removed. My preferred form of spring bracket is put in place as indicated with the lever, stirrup, coil spring and the like all assembled. The same spring links which previously Went from the spring to the springperch or bracket are coupled up to the free end of the lever and the load of the car is allowed to settle down upon the coil spring. The weight of the car holds all the parts in proper assembly and operating position and that is all that is necessary. The long conical coil spring is sturdy and din-able but yet gives o the slightest vibration or bump throughout its entire length and the use of this lever and spring arrangement reall results in effect in lengthening the effectlve length of the spring and makin a much smoother, easier riding vehicle and because of the sensitive characteristics of the coil spring the stifl and rigid fiat leaf spring is permitted to give for heavy shocks and jolts but the vehicle is protected from slight vibrations by the ready operation of the coil spring.

I claim:

1. A spring suspension for vehicles comprising a bracket adapted to be secured to the running gear, a spring supporting platfiOrm projecting laterally therciironr a,

conical beehive spring thereupon, a lever pivoted at one end upon said bracket and connected at its other end by a link to the leaf spring directly supporting the body of said vehicle. a stirrup resting upon the top of said conical spring extending below it and pivoted "on both sides to said lever intermediate its ends.

2. A spring suspension for vehicles comprising a-bracket adapted to be secured to the running gear, a spring supporting platform projecting laterally tl'ierefrom, a conical beehive spring thereupon, a-lever pivoted at one end upon said bracket and connected at its other end by a link to the leaf springdirectly supporting the body of said vehicle,

- the running gear,

a stirrup resting upon the top of said conical spring extending below it and pivoted on both sides to said lever intermediate its ends, said stirrup touching said conical spring on its top only.

3. A spring suspension for vehicles comprising a bracket adapted to be secured to the running gear, a spring supporting plat form projecting therefrom, a conical beehive spring thereupon, a lever pivoted at one end upon said bracket and connected at its other end by a. link to the leaf spring directly supporting the body of said vehicle, a stirrup resting upon the top of said conical spring extending below it and pivoted to said lever intcrn'iediate its ends, said stirrup touching said conical spring on its top only.

4. A spring suspension for vehicles comprising a bracket adapted tobe secured to the running gear, a spring supporting plat form projecting laterally therefrom, a coil spring thereupon, a lever pivoted at one end upon said bracket and connected at its other end by a link to the leaf spring directly supporting the body of said vehicle. a stirrup resting upon the top of said coil spring extending below it and pivoted on both sides to said lever intermediate its ends.

5. A spring suspension for vehicles comprising a. bracket adapted to be secured to a spring supporting platform projecting laterally therefrom, a single coil spring thereupon, a lever pivoted at one end upon said bracket and connected at its other end by a link to the leaf spring directly supporting the body of said vehicle, a stirrup resting upon the top of said coil spring extending below it and pivoted ondboth sides to said lever intermediate it's on s.

In testimony whereof, I affix my signature iuthe presence of two witnesses this 30th day of December, 1918.
